Description
Technical field
The utility model belongs to a kind of low-voltage controling appliance, and is particularly a kind of not by mechanical disjunction, uses master controller under the contactless card that optoelectronic switch has analog quantity output simultaneously.
Technical background
Master controller is used in the power drive operation circuit more, as the usefulness of the control of the frequent transitions of gearing.Control Technique of Microcomputer is widely used in the commercial production field now, and artificial transmits control signal to microcomputer, or adjusts the control signal means, generally adopts the chattering type master controller to carry out.It is the rotation by the control cam bit, comes to transmit control signal to microcomputer by the concavo-convex program section breaker of cam bit, realizes the control to electric equipment.This chattering type master controller has the following disadvantages in Control System of Microcomputer:
1. contact assembly is long-term use after, its contained spring will produce fatigue deformation, loose contact, air corrosion, contact resistance increases, and the control signal of Control System of Microcomputer is weakened control signal, blackout when serious, normally the carrying out of influence production.
2. contact assembly contacts with cam bit is concavo-convex, and long-time the use produces mechanical wear, causes the closing of contact not tight, influences signal output.
3. the master controller of selsyn formula analog quantity output, it is output signal by selsyn, after transformer, phase sensitivity bridge are handled, obtain needed analog signals again, complex circuit, bulky, the trouble spot is many, brings inconvenience for user's working service.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of analog quantity to export master controller under the contactless card, and is easy to adjust, fast, and accurately.
The purpose of this utility model is achieved by the following technical solution: it comprises operating rod, bent axle, elevating arc, gear, anti-dazzling screen, optoelectronic switch, fixed head, square steel, shaft coupling, potentiometer composition, it is characterized in that: on rotating square shaft, connect firmly and the elevating arc meshed gears, and string is adorned anti-dazzling screen on square shaft, square shaft connects firmly potentiometer by shaft coupling, at anti-dazzling screen side assembling optoelectronic switch, relay output circuit plate is set simultaneously.
The rotation of above-mentioned square shaft drives anti-dazzling screen and rotates, and produces the switch output quantity by the optoelectronic switch pilot relay.When optoelectronic switch was blocked by anti-dazzling screen, optoelectronic switch disconnected; When not blocking, the optoelectronic switch closure.The rotating band electrokinetic potential device of square shaft rotates simultaneously, by potentiometer, the firm and hard existing analog quantity output of relay output circuit.
Owing to adopted above technical scheme, the utlity model has following advantage:
1. because analog quantity output is continuous, and control output by potentiometer, therefore, can reach required voltage by regulator potentiometer, adjustment work is simple, and control output is convenient, accurately, adjusts work efficiency and is greatly improved.
2. potentiometer can significantly be adjusted, and also can carry out trace adjustment
3. compact overall structure, dependable performance can be contactless, no pressure, no-spark sends the electrical control instruction quickly and accurately.

Embodiment
Shown in Fig. 1-5, operating rod 3A links to each other with elevating arc 3L by bent axle 3K, gear 14 is fixed on the square shaft 15, and be meshed with elevating arc 3L, anti-dazzling screen 6 is connected on the square shaft 15, four square steel 5 squarelys are fastened on the fixed head 4 by screw, fixed head 4 again by screw retention on housing 3, optoelectronic switch 7 is installed on four square steel 5.Four hexagonal prisms 8 and up and down the mechanism between two fixed heads be called the gear detent mechanism, the gear detent mechanism as shown in Figure 5, comprise spring 17, rocking arm 16, rocking shaft 9, roller 18 and ratchet 10, spacing position of zero-bit and the spacing position of gear are arranged on the ratchet 10, ratchet 10 strings are on square shaft 15, two rocking arms 16 are fixed on the rocking shaft 9, in roller 18 is housed, and ratchet 10 is clipped in the middle.Potentiometer links to each other with the top of shaft coupling 12, and is positioned at dome 11.Three terminals of optoelectronic switch 7 are respectively the power supply positive input terminal, earth terminal and signal output part, the terminals of potentiometer are respectively earth terminal, sliding end, power supply positive input terminal and power-input end, the power supply positive input terminal of optoelectronic switch 7, the power supply positive input terminal of earth terminal and potentiometer, earth terminal all with the power supply positive output end of relay output circuit plate 13, earth terminal links to each other, the signal output part of optoelectronic switch 7 all links to each other with the signal input part of relay circuit output board 13 with the sliding end of potentiometer, the power-input end of potentiometer link to each other with the power-output terminal of circuit output board 13 (above-mentioned each element is electrically connected and is prior art, thereby diagrammatic sketch is not provided).The course of work: master controller and worktable are fixed, and operating rod 3A is positioned on the work top, and all the other mechanisms are positioned under the table top.Operating rod 3A seesaws during work, operating rod 3A drives elevating arc 3L by bent axle 3K and rotates with its meshed gears 14, gear 14 drives square shaft 15 and anti-dazzling screen 6 rotates synchronously, when anti-dazzling screen 6 shading light electric switches 7, relay disconnects, meanwhile do not have switching value output, control circuit disconnects; Otherwise then control circuit is connected.Master controller is formed many group control circuits by a plurality of anti-dazzling screens and a plurality of optoelectronic switch, regularly connects and the branch deenergizing by closed routine, thereby reaches the control purpose.When seesawing with hand operation handle 3A, square shaft rotates along with the motion of operating rod 3A, thereby driving potentiometer rotates, the rotation of potentiometer promptly is the slip of the sliding end of potentiometer, like this, the resistance of potentiometer is changed, because potentiometer links to each other with relay output circuit plate 13, therefore, the resistance of circuit board also can change, and also will make the output terminal of circuit board that different analog quantity output is arranged.The course of work that operating rod 3A and resetting-mechanism reset: operating rod 3A and bent axle 3K are being with fan-shaped restoring board 3B 2 to rotate around the shaft during work, curved surface 3H on the fan-shaped restoring board 3B depresses rocking arm 3C by bearing 3I, and rocking arm 3C emits 3D that the spring 3E that one end is fixed on the spring 3F is compressed by spring.When openhanded when opening operating rod 3A, the spring 3E that is supported on the spring abutment 3F discharges gradually, by the rolling between the curved surface 3H on bearing 3I on the rocking arm 3C and the fan-shaped restoring board 3B, make operating rod 3A get back to the zero-bit position, and rely on circular arc camber 3J and the location of the bearing on the rocking arm 3C on the fan-shaped restoring board 3B.When operating rod 3A gets back to zero-bit, potentiometer is also got back to zero-bit, there is not the output of analog quantity this moment, in order to guarantee that potentiometer can get back to zero-bit accurately, adopted the gear detent mechanism, when operating rod 3A is positioned at zero-bit, 18 on roller is positioned at the spacing position of zero-bit of ratchet 10, when operating rod 3A was positioned at different gears, 18 on roller was positioned at the spacing position of different gears, so just can guarantee that zero-bit is accurate and gear is clear.
